To all whom, it may concern:

Be it known that I, I'IOWARD F. SNrnnii, a citizen of the United States,residin at Newton, in the county of Jasper and tate of Iowa, haveinvented acertain new and useful Dumping-Wagon, of which the followingis a specification.

The object of my invention is to prov de a dumping wagon of simple,durable and inexpensive construction so arranged that the operatorriding upon the wagon may, u on approaching the point where it is desireto damp, operate a lever to thereby cause the machinery carried by thewagon and operated by a traction wheel thereof to elevate the forwardend of the wagon and to dump the load at the point desired.

A further object is to provide means'for automatically stogpinfi thetilting movement of the wagon be w on it has reached its limit ofmovement, and thereby prevent breakage of the tilting wagon bed or anyof the operative arts which might otherwise be caused by t e failure ofthe operator to release the tilting mechanism.

A further object is to provide sim le durable and inexpensive means forcon ro ing {)hei return movement of the tilting wagon Further objectswill appear hereafter in the following description.

. My invention consists in the construction, irrangement and combinationof the 'various parts of the device, whereby the objects COHiAJm latedare attained, :as hereinafter more ullyset forth, pointed out in myclaims, and illustrated in the accompanying drawings, in which- Figure 1shows a side elevationof a wa on embed in my invention with arts hro enawav s ow certain details-o construction. The dotted lines in said fl reshow the position of the wagonbed-w en dumpm Fig. 2.shows a horizontalsectional viewthrough the sidesmfrthadumping wagon bed to illustrate themechanism for tilting thewagon beds Fig. 8j'shows an enlarged detailview, Part1 --in section, of

drum sha Land:

Referr ngeto. the accompanyingdraw ngs I; have, used .th referencenumeral 10. to in-f dicate. the'runnmg gear. of theiwagomwhioh s 701{the ordinary construotionm e': Mounteduon the running gear il ildlilvrt was tionary wagon bed 11, having at its forward end the uprightframe 12, upon which are mounted the drivers seat, 13, and the footboard 14.

Rotatably mounted in the stationary wagon bed 11 is a shaft 15, havingkeyed to one end thereof a sprocket wheel 16. This sprocket wheel 16 isconnected by a s rocket c ain 17 with a sprocket wheel 18 xed to one ofthe traction wheels, so that when the wagon is advanced the shaft 15will be constantl rotated.

Ad acent to the sprocket wheel 16 is a bearing 19 secured to thestationary wagon bed 11, and on the other end of the shaft 15 is abearing 20 secured to the wagon bed 11. This bearing 20 is provided atone end withone or more inclined teeth or lugs 21, shaped similar to theteeth on a ratchet clutch.

Adg'acent to the bearin 20 is a hub 22 rotatab y mounted on the s aftand provided with teeth'23 to coact with the teeth 21. This hub 22 isalso provided with a downwardly projecting arm 24, and said parts are soarranged that when the arm is moved forwardly the hub 22 will be movedlongitudinal of the shaft 15 away from the bearin 20 on account of saidinclined teeth. T e firpose of this longitudinal movement will. madeclear hereinafter, and it is only necessary that this movement becomparatively slight in order to accomplish the purposes for which it isintended.

Looselymounted upon the shaft 15, ad- {acent to the hub 22 is a drum 25,one end of he drum being in engagement with the hub 22 and the other endofthe drum being rovided with aflan e 26 having a tapere interior 27,and a so having its eriphery sha ed receive a band brake. his band bra eis indicated b the numeral 28 and is attached atone en .to astationaig'cross piece 29 rand-is then passed upwar ly and rearwar lyover. the flange 26, and its other and extends forwardl below the flange26 as clearly shown in *ig. 1, and the rod 30 is attachedtothe latterend of the hand brake. This. rod extends forwardly and. is provided. atits forwardend with .a sprin l'i'yvhichinormally holds-it to its forwarlimitof movement and hence normally holds the. band brake tight u on theflange 26 and thereby revents rotat on of the drum 5.

i; In Q or to release the band brake I provide a bell-cranklever 32having a rod 33 attached to it and connected to a foot lever 34 on thefoot rest 14, the parts being so arranged that when the foot lever 84'is depressed the spring 81 will be com ressed-as re uired to release theband bra e.

l ixed to the shaft 15, adjacent to the flange 26 is a cone shapedmember 35 so arranged that when the flange 26 is moved longitudinal ofthe shaft by means of the hub 22, the said flange will frictionallyengage the cone 35 so that the'drum will be rotated in unison with thecone.

Between the drum and cone I have placed an expansible coiled spring 86for normall holding the drum out of engagement wit 1 the cone.

Mounted on top of the stationary wagon bed 11 is a tilting wagon bed-37pivotally connected with the wagon bed 11 by a pivot pin 38. This pivotin is arran ed in the rear of the center 0 the wagon d 87 so that themajor portion of the weight cf the wagon bed 37 is in advance of saidpivotal oint.

Beneath the wagon bed 87 is a cross piece 89 attached to the wagon bed87. Fixed to this cross piece is a rope or cable 40 extended forwardlunder the wagon bed 87 and then upwar 1y over a pulley 41at the top ofthe upright frame 12, then downwardly under a pulley 42 at the forwardportion of the stationary wagon bed 11, and then rearwardl to the drum25, its rear end bein fixe to and wound'upon said drum. y thisarrangement it is 'obvious that when the drum is rotated by theshaft 16the ro e or cable will be wound u on it and the orward end of the wagonb beelevated; v I I y I have provided for operating the arm-24 will , asrequiredto throw'the drum'into operation as follows: Pivoted tothe-lower end of the arm 24 is a rod 43 extended forwardlX and connectedto a bell-crank'lever 44.

foot lever 45 is mounted upon the footrest 14 and connected b 1a link-46 with the'bellcrank 44,hence w en said-lever 45 is-de pressed the drum25 is moved" toposition in engagement withthe cone- 85 'and "is therebyrotated-"with the shaft'llir lfgthe operator should for any reason ail=to release the lever-45 when'the tiltingwagon bed is at itszlin'iit of:movementythe-tiltmg wagon bed would be'elevatedtoo far andim urytothe-device might possibl result. To prevent this I have provideautomatic means for stopgilng' the movement of the tilt ng; wagonflwhemitrhes {reached its upper limit as follows: Fixed tc the'ropeorcable'ao m ja stop 47',"and attached tothe lever 4A5 isw chain :48having -si'locpywon one end g'thr'ou h whi 40 is passeda -g hesepartsdr'e s01 "arran thatwl eirthd'stop wengages the loop '4 it willautomatically move the lever 45 to posi-i; tion for raisin the operatorsfoot, and

thereby permitting the sprin 36 to throw the drum 25 out of frictionacontact with the cone 85.

In ractical use the we on is moved over a fiel and is loaded in t eordinary manner. When it is desired to discharge the contents of thewagon the operator presses upon the foot lever 45 and thereb causes thedrum 25 to be rotated in the irection re uired for winding u% the ropeor cable an li tilt-in the we on cd. When it has been tilte to its imitthe movement is automatically. sto ped and the operators foot is raisedso t at if for any reason the operator should fail to release the lever45 at the roper time it will be released auto matica y.

The wagon bed will be automatically held 3 in any position in which itis placed by the hand brake 28 so that after the load is dis-tchargedvand the drum 25 released from enga ment with the cone 35, thewagon bed wi not drop to its normal position; it will, however, returnby gravity to its horizontal fposit-ion if the operator presses upon thecot lever 34; hence the return movement of the we on bed is entirelywithin the control of t e operator and may be accomplished slowly andeasily without anfi shock or jar to the wagon.

y the construction herein disclosed the operator while seated upon thewagon may readily and easily dump the contents of the wagon and causethe wagon bed to be returned to its normal position without leaving theseat and without stopping. the we n. claim as my invention. v
